TPS2012PWR TI USB Power Switch | 2-Channel, 0.5A, Current-Limited

Product Overview

The TPS2012PWR from Texas Instruments is a dual-channel, current-limited power-distribution switch designed for USB and other hot-swap applications. It provides up to 0.5 A per channel and operates over a supply range of 2.7 V to 5.5 V. The device features low on-resistance (70 mΩ typical) to minimize voltage drop and power dissipation. It includes overcurrent, overtemperature, and reverse-current protection, making it ideal for robust power management in portable and industrial systems.
